Adjustable, configurable storm inlet filter
View Patent ↗System and apparatus for filtering drainage which includes a configurable and adjustable rigid frame, hanger support structures adapted to contact a surface of a drainage structure, and a sediment bag. The frame may be adjusted or configured by modifying the location of connecting fasteners and/or by altering the orientation of frame components. Additional embodiments provide for an overflow gap comprising a vertical distance between an above grade surface of a drainage structure and the rigid frame, wherein the overflow gap is capable of allowing runoff to bypass the sediment bag when the sediment bag is obstructed. A configurable lifting tool device adapted to lift inlet grates and inlet filter devices includes a lifting bar, a plurality of connectors, a plurality of lifting arms, and a plurality of lifting hooks adapted to contact a grate and/or an inlet filter device lifting bar.
1. An apparatus for use in a drainage filtering system comprising:
a corner bracket including two surfaces adjoined at an angle to form a corner; and a frame rail contact arranged on a bottom portion of the corner bracket and configured to attach to a frame rail, the frame rail being attachable to a sediment bag; and a hanger configured to support the corner bracket by contacting an above grade surface of a drainage structure such that, when attached, the frame rail and the sediment bag are each below the grade surface of the drainage structure when the hanger contacts the above grade surface.
2. The apparatus of claim 1 , wherein the corner bracket includes a hole configured to receive a fastener, and wherein the corner bracket is attachable to the frame rail using the hole and the fastener.
3. The apparatus of claim 1 , further including an overflow gap comprising a vertical distance between the corner bracket and the hanger, wherein the overflow gap is configured to allow runoff to bypass the sediment bag attached to the frame rail by allowing the runoff to flow over the frame rail and below the hanger.
4. The apparatus of claim 1 , wherein the hanger is adjustable relative to at least one of the surfaces of the corner bracket, thereby providing for rotation of the hanger relative to the corner bracket to accommodate the hanger contacting the above grade surface of the drainage structure.
5. An apparatus for use in a drainage filtering system comprising:
a bracket including a frame rail contact arranged on a bottom portion of the bracket, wherein the frame rail contact is attachable to a frame rail, wherein the frame rail is attachable to a sediment bag, and wherein the frame rail is curved; and a hanger configured to support the bracket by contacting an above grade surface of a drainage structure such that, when attached, the frame rail and the sediment bag are each below the grade surface of the drainage structure when the hanger contacts the above grade surface.
6. The apparatus of claim 5 , wherein the bracket includes a hole configured to receive a fastener, and wherein the bracket is attachable to the frame rail using the hole and the fastener.
7. The apparatus of claim 5 further including, an overflow gap comprising a vertical distance between the bracket and the hanger, wherein the overflow gap is configured to allow runoff to bypass the sediment bag attached to the frame rail by allowing the runoff to flow over the frame rail and below the hanger.
8. The apparatus of claim 5 , wherein the hanger is adjustable relative to the bracket, thereby providing for rotation of the hanger relative to the bracket to accommodate the hanger contacting the above grade surface of the drainage structure.
9. An apparatus for use in a drainage filtering system comprising:
a corner bracket including a frame rail contact arranged on a bottom portion of the corner bracket, wherein the frame rail contact is attachable to a frame rail that is attachable to a sediment bag, wherein the corner bracket comprises two planar surfaces of a rigid material joined at a 90 degree angle, and wherein the planar surfaces include a first plurality of holes; a hanger support structure configured to support the corner bracket, wherein the hanger support structure includes a second plurality of holes; and a hanger connected to the hanger support structure, wherein the hanger is adapted to contact an above grade surface of a drainage structure such that, when attached, the frame rail and the sediment bag are each completely below the grade surface of the drainage structure when the hanger contacts the above grade surface.
10. The apparatus of claim 9 , wherein the hanger support structure is connected to the corner bracket by a fastener through the first plurality of holes and the second plurality of holes.
11. The apparatus of claim 9 , wherein the vertical height of the hanger support structure is capable of being adjusted by changing the position of the fastener with respect to the first plurality of holes and the second plurality of holes.
12. The apparatus of claim 9 wherein the orientation of the hanger support structure is capable of being adjusted to contact a surface of a curb by changing the position of the fastener with respect to the first plurality of holes and the second plurality of holes.
13. A method of employing an apparatus for use in a drainage filtering system, the method comprising:
attaching a frame rail to a bracket, the frame rail being attachable to a sediment bag, the apparatus comprising:
a bracket including a frame rail contact arranged on a bottom portion of the bracket, wherein the frame rail contact is attachable to the frame rail, and
a hanger configured to support the bracket by contacting an above grade surface of a drainage structure such that, when attached, the frame rail and the sediment bag are each completely below the grade of the drainage structure when the hanger contacts the above grade surface.
14. The method of claim 13 , wherein the bracket comprises a corner bracket including two surfaces adjoined at an angle, thereby forming a corner.
15. The method of claim 13 , wherein the bracket is attachable to a curved frame rail.
16. The method of claim 13 , wherein the bracket includes a hole configured to receive a fastener, and wherein the bracket is attachable to the frame rail using the hole and the fastener.
17. The method of claim 13 , wherein the apparatus includes an overflow gap comprising a vertical distance between the bracket and the hanger, and wherein the overflow gap is configured to allow runoff to bypass the sediment bag attached to the frame rail by allowing the runoff to flow over the frame rail and below the hanger.
18. The method of claim 13 , wherein the hanger is adjustable relative to the bracket, thereby providing for rotation of the hanger relative to the corner bracket to accommodate the hanger contacting the above grade surface of the drainage structure.
